FOOD-CUTTER.

SPECIFICATION formingpart of Letters Application filed August 24, 1903.

To all whom it may concern! Be it known that I, GEORGE A. CoLToN, a citizen of the United States, residing at Phoenix, in the county of Oswego, State of New York, have invented certain new and useful Improvements in'Food-Cutters, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to a food-cutter, and particularly to a structure embodying a cyl" inder having a feed-screw therein and a cutting-disk at'the discharge end of said screw. The invention has'for an object to improve the construction of screw so as to prevent the feedingof material away from the axi'sthereof and "also to improve the construction 'of the. rotatable cutting-disk and a fixed plate cooperating therewith, so as to securethe most eflicient results and a cutting action upon all portions of the disk.

A further object of the invention is to improve the construction of the handle, by which it maybe removed Whendesired and the feeds'crew disconnected therefrom at any time.

Other and further. objects andadvantages of the invention willbe hereinafter set forth and the novel features thereof defined by the ap pended. claims. T I

In the drawings, Figure 1 is'a central vertical section of the invention with the clamping portion thereof in elevation. Fig. 2 is an endelevationat the handle end of the device. Fig. '3'is a detail vertical section of a portion ofthe feed-screw. Fig. 4: is a plan of the fixed disk; Fig. 5 is a perspective of the movable cutting-disk, and Fig. 6 is a central vertical section therethrough.

Like'letter's of reference refer to like parts in the several figures ofthe drawings.

The letter A designates a cylinder or body end with the usual'feed-hopper A and at its lower portion with a depending arm or standard A having any desired form of securing means connected therewith-for instance, a fixed lug'A extending laterally from the able-clamping-screw A, carried by the lower end A of the standard, said screw being provided with an 'operating-handle'A ofany con- Patent No. 760,779, dated May 24, 1904.

Serial No. 170,591. (No modeli) struction. For convenience of construction the casing of the cutter is formed of two parts and secured together by rivets or bolts in-the usual manner. The interior of the cylinder A is provided with ribs A, spirally disposed upon the walls, as usual in this art, and at one end a bearing A is provided and adapted to receive the axis B- of the feed-screw B. The threads of this screw are disposed in the usual manner; but instead "of terminating in a straight edge, as heretofore in this art, they are provided upon their peripheries with hanged or laterally-extending portions B which are formed parallel to the axis of the screw and upon the advancing face with the curved surfaces B the object thereof being to feed the material carried by the screw both forwardly and downwardly toward the axis thereof. When the straight-edge screw is used, the material is thrown toward the periphery of the screw and dragged or mashed between the same and the ribs of the cylinder,

and the cutting action is largely confined to the outer edge of the disk.

At the discharge end of the feed-screw a fixed plate 0, provided with suitable apertures C for the feed of material therethrough, is secured in position in 'any desired mannerfor instance, by means of a radially-extending lug C adapted to enter a suitable socket or recess A in the casing, and this plate is provided with 'a central aperture C within which the point of' connection, so as to resist the strain due to the cutting action. Thetzuttingdisk D is provided with any suitable number of apertures D and adapted to be formed of steel suitably tempered, these apertures being tapered inward,'so asto-secure a free dis charge of cut material therefrom. The arched portion D forms a curved face, in contact with which the securing-nut E is adapted to bear, this nut being provided with a conically-recessed portion E in order to secure a large surface in contact with the arched portion D of the cutting-disk and thus more firmly hold it in its adjusted position upon the shaft of the feed-screw.

For the purpose of removably securing the handle F to the shaft or axis of the feed-screw the latter is provided with an extended squared portion B adapted to fit a similar recess F at the upper end of the handle, while the inner face of the handle is provided with a recessed portion F to receive the bearing A extending outwardly from the cylinder, and this recessed portion is provided upon one face with a peripherally-extending segmental rib F Cooperating with this rib and disposed upon the end of the cylinder portion of the cutter are lugs F, behind which the rib is adapted to fit and travel in the ordinary operation of the handle, so as to prevent an accidental disengagement thereof. When it is desired to remove the handle, the cutting-disk and plate, together with the feed-screw, are removed from the cylinder and the handle then turned to bring the segmental flange out of contact with one of the lugs, so that by a lateral movement thereof it may be removed from the remaining lug, thus permitting all parts of the cutter to be separately cleaned.

In the operation of the invention it will be seen that the material fed into the hopper is carried by the feed-screw outward and forced through the fixed plate at the discharge end of said screw, where the portions projected through said plate are engaged by the cutting-disk and separated by a shearing action, so as to secure a perfectly clean cutting of the material without any chopping, mashing, or mangling thereof. It will also be apparent ,that by removing the clamping-nut the cutting-disk may be removed and replaced by a different size, while the fixed plate cooperating with said disk is capable of instant removal and replacement by lifting the same from its securing-socket. When these are removed, the feed-screw can be drawn directly outward and the handle separated from the casing by an upward movement thereof. The parts may be assembled by a reverse operation and are so simple in construction that they are capable of operation and assemblage by any person. The construction of the feedscrew having the laterally-disposed flanges upon its blades exerts a forcing power at nearly a right angle to the axis of the screw, so that the material which is ordinarily carried outward from the axis of the screw and fed only to the outer openings of the cutter is carried forward in an even body, thus securing an equal cutting action upon all the surfaces of the disk. The formation of this disk is also an important improvement in that it permits the same being formedof cheap material in which the cutting-apertures may be punched and the material then tempered, so as to secure the most eflicient results in the wear and action thereof.

It will be obvious that changes may be made in the details of construction and configuration without departing from the spirit of the invention as defined by the appended claims.

Having described my invention and set forth its merits, what I claim, and desire to secure by Letters Patent, is

1. In a food-cutter,a cylinder provided with a feed-hopper at one end, cutting means at the discharge end of the cylinder, and a feedscrew extending'from the hopper to the cutting means and having the periphery of its blades extended parallel to the axis of the screw throughout its length and toward the discharge end thereof.

2. In a food-cutter, a feed-casing having solid walls, a fixed plate and rotatable cutter at the delivery end thereof, and a feed-screw comprising spirally-disposed blades having their periphery extended parallel with the axis of the screw throughout its lengthwithin the casing and toward the discharge end thereof.

3. In a food-cutter, a cylinder,a feed-screw, a fixed apertured plate secured in position by said cylinder, an apertured cutting-disk having an angular central aperture with arched walls to engage squared faces upon the shaft of said screw, and a nut for securing said disk in position.

6. In afood-cutter, acylinder, afeed-screw, a fixed apertured plate secured in position by said cylinder, an apertured cutting-disk having an angular central aperture with arched walls to engage squared faces upon the shaft of said screw, a nut having a concaved recess adapted to seat upon the arched portions of said disks, a radial projection from said plate adapted to enter a socket in said cylinder, a bearing portion at the feed end of the cylinder for the shaft of said screw, an angular 7 central aperture.
